This Sunday is March fourteenth, 3.14, aka Pi Day. Something about celebrating the Greek letter that represents a numerical constant appeals to my inner dork.

The obvious thing to do to celebrate Pi Day is to make pie! Not only is pie delicious but its round shape is the perfect jumping off point to challenge children (or yourself) to practice geometry with π.

If you are a blogger and would like to participate, I am hosting a Pi Day Pies blog carinval on Sunday. I will post a recipe with a Mr. Linky on 3.14 at 1:59 AM (first six digits of π are 3.14159) for you to add your recipe, story, or song about pies/pis. Please join in the math geek fun!
